Summary

• Mines are splash damaging traps that are like the Bomb. They do low damage in a relatively large area, pushing troops back and depending on the mode set, they can damage either ground or air troops, but not both at the same time.
• They prove to be even better than the Bomb, due to being able to damage troops in 1 second compared to the Bomb's 2.5-3 second delay before effect, as well as the ability to be configured to either ground or air.
• Although not doing much damage, the Mines still have power in number and can take out support troops or hordes of low-hitpoint units.
• The Mine explodes after an enemy comes within 4 tiles of it, causing splash damage to every ground or air enemy troops within 5 tiles. This delay means that you'll want to place the bomb in an area where troops are likely to remain for a period of time, such as right next to a building they're attacking.
• Like any other traps in the Builder Base, the Mine does not need the Master Builder or O.T.T.O for construction, however, they are required for upgrading.

Strategies

Defensive Strategy

• Try to use Mines on the outside of the map, so it can severely damage sniping Sneaky Archers.
• Placing two Mines together will kill Sneaky Archers and Beta Minions of relative level. Three Mines together will kill Raged Barbarians of relative level.
  • However, this uses up the majority of your Mines, so it is not recommended.
• Setting Mines to Ground would better protect your base if you are losing to ground attacks. Setting them to Air would protect your base from air attacks, if you are losing against them. Set half-and-half if you are losing to both type of attacks.
• You can stop a Bomber from throwing its first bomb by placing a Mine near the area, which allows your defenses to one-shot it.
• Use Mines set to air around your Firecrackers to help it take out swarms of Beta Minions.
• A single Mine set to air can stop a horde of Bats (spawned by Night Witches) from swarming your base.
• When set to Ground mode, it can stop a mass of Skeletons spawned by Drop Ships but only if other ground units, such as the Battle Machine, trigger the trap.
• Put Mines (in air mode) around your Builder Hall if it is located in a corner. This will disrupt any enemy Air Troops which approach your base from that corner. It is even more powerful if you place your Roaster and/or Air Bombs near the Builder Hall, which can quickly overwhelm enemy air troops.

Offensive Strategy

• Mines are weak against high-hitpoint troops such as a Baby Dragon, or a Battle Machine.
• Make sure to test for Mines near Walls when using the Bomber with another troop, such as a Raged Barbarian, so the Bomber can be successful in destroying the Walls.
• Make sure to stagger your troops when sending them into the base, especially if they are low-hitpoint troops, so a Mine cannot hit them all at once.

Upgrade Differences

• The Mine undergoes significant visual differences at levels 3, 4, 5, 7, and 9.
  • At level 1, it appears to be a barrel strapped with ropes with a timer on it that has red wires connecting it to the barrel.
  • At level 2, the ropes on the barrel are replaced with metal bands.
  • At level 3, the barrel gets a raspberry red paint job.
  • At level 4, the barrel turns into a spherical Mine.
  • At level 5, the timer is removed and the Mine gains metallic studs on the surface. The band in the middle becomes smaller.
  • At level 6, metal horns replace the studs.
  • At level 7, the Mine gets a black paint job, a skull face appears on it, and the horns are replaced by grey studs.
  • At level 8, the studs are replaced by spikes.
  • At level 9, the Mine gains a bigger capsule shape. The sides have a center circle separated from the rest and what appears to be its mechanism and a glowing part. The spikes are gone.
  • At level 10, the glowing part of the capsule is covered up with metal. The Mine also gains four spikes on each corner.
  • When switched to air mode, the Mine will appear to float, supported by a metal chain.
